Israel-based Quantum Machines has launched QUAlibrate, an open-source framework designed to slash quantum computer calibration times from hours to minutes — tackling what experts call quantum computing’s most stubborn operational bottleneck.
During controlled tests at the Israeli Quantum Computing Center, QUAlibrate demonstrated 140-second multi-qubit calibrations — reporting 98% improvement over conventional methods.
The system employs a novel graph-based architecture that breaks calibration into parallelizable modules for operations like Rabi oscillations and spectroscopy, according to a press statement. This breakthrough comes as researchers grapple with increasingly complex calibration processes. A 2024 Physical Review Applied study found that today’s 100-qubit systems require full recalibration every 24 hours due to parameter drift.
Early adopters of QUAlibrate — including UK-based quantum processor maker Oxford Quantum Circuits and Taiwan’s Academia Sinica — report order-of-magnitude time savings. Quantum computing startup Qolab’s CTO John Martinis said calibrations that once took two hours now complete in just ten minutes, according to the press statement.
The framework arrives amid a broader architectural shift in quantum computing. “QUAlibrate reflects a broader realignment toward open, modular orchestration that decouples critical functions from proprietary hardware,” noted Daniel T, senior analyst at QKS Group. “This undermines traditional vendor lock-in models and better positions the industry for heterogeneous quantum ecosystems.”
While QUAlibrate supports live data visualization and superconducting qubit protocols, it currently requires Quantum Machines’ proprietary OPX control hardware. “We care both about how long it takes to calibrate and how good the calibration is—two things that sometimes collide — and this impacts overall system performance,” Yonatan Cohen, co-founder and CTO of Quantum Machines, said in a statement.
Cohen’s reference to this speed and quality tradeoff mirrors what analysts identified as a critical transition phase: while some labs still manage calibration manually, the field is clearly moving toward automation.
“The true value lies in preparing for future systems,” emphasized Daniel. “As we approach fault-tolerant quantum computing, calibration must evolve from a manual process to an automated system function.” QUAlibrate’s open-source design and multi-qubit support position it as a potential bridge between today’s fragmented tools, according to Daniel.
The standardization crisis
McKinsey’s 2024 Quantum Monitor highlighted a growing “standardization crisis” in quantum computing, naming bespoke qubit calibration among six core challenges.
IBM’s Qiskit Pulse operates exclusively on IBM hardware, Rigetti’s PyQuil is tailored to its superconducting systems, and Google’s Cirq — though nominally open — is largely optimized for Google Sycamore processors. Commercial tools like Q-CTRL’s Black Opal offer AI-powered calibration but remain closed-source, while academic platforms such as Delft University’s Quantify address narrow research needs without enterprise-scale readiness.
QUAlibrate seeks to bridge this divide through graph-driven automation and planned integration with Nvidia DGX Quantum. “Frameworks like this are crucial,” said Daniel. “They abstract hardware complexity while enabling standardized workflows essential for enterprise adoption.”
With the quantum control systems market expected to grow at a 27.3% CAGR—from $74.24 million in 2024 to $383.71 million by 2031, per Intel Market Research — QUAlibrate’s open-source foundation and multi-qubit support position it well for this expanding sector. Still, its dependence on Quantum Machines’ proprietary OPX hardware presents a barrier for labs using alternative systems.
“Yet its early automation capabilities may prove strategically vital. “QUAlibrate embeds critical automation infrastructure now,” Daniel said, “positioning future quantum systems not just for greater computational power, but for the operational resilience enterprises will demand.”
